I'm looking for some information regarding concurrent sessions in Cisco IPS42xx models. Does the IPS has specific calculation when measuring the sessions? I'm comparing with Cisco SCE because I found out that SCE does bundle multiple flow/sessions into single flow/session like for FTP, SIP and few other protocols. So does the IPS do the same?
I understood that both IPS and SCE are performing different functions and understand that both are measuring concurrent sessions when performing their functions. But I think that the sessions for SCE and IPS are calculated differently. Do you have any details about this?
